开发一个简易的Start

• 创建Springboot项目

• 导入依赖

• 整体工程结构图

• 删除build

• configgg删除主启动类配置

package com.xc.demostart;import com.xc.demostart.demo.test;import lombok.Data;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;@Configuration@ConfigurationProperties(prefix = "xc.start")@Data@ComponentScanpublic class DemoStartConfig {    private String accessKey;    private String secretKey;    @Bean    public test xcApiClient() {        return new test(accessKey, secretKey);    }}

• 写下你想要实现的功能(这里我将简单地实现以下ak和sk返回我的配置)

package com.xc.demostart.demo;/** * @author xc * @date 2023/4/8 19:25 */public class test {    private String ak;    private String sk;    public  test(String ak,String sk) {        this.ak = ak;        this.sk = sk;    }    public String printAkSk() {        return "ak: "+ak+"sk: "+sk;    }}

在resources下新建包META-INF，Spring新配置文件.factories

# spring boot starterorg.springframework.boot.autoconfigure.EnableAutoConfiguration=com.xc.demostart.DemoStartConfig

然后mvn install后到本地仓库进行测试

• 测试

随便创建一个maven项目

在pom.将刚刚的startttart引入xml

<dependency>            <groupId>com.xc</groupId>            <artifactId>demo-start</artifactId>            <version>0.0.1-SNAPSHOT</version>        </dependency>

application.在yml中配置自己的ak，sk

xc:  start:    access-key: xcxc    secret-key: 666

注意xc.start是刚刚在config配置文件中的prefix

@SpringBootTestclass TestStartApplicationTests {    @Resource    private DemoStartConfig demoStartConfig;    @Test    void contextLoads() {        System.out.println(demoStartConfig.demoStart().printAkSk());    }}

控制台运行后输出

与我们直接写的配置相同，说明start开发成功
